Fructose Face-Off: plantains, underripe, raw vs apples, gala

Evidence-based comparison — data from USDA+ODS-NIH PURINE DATABASE Release 2 (March 2025)

Fructose Comparison

Food	Fructose (g/100g)	Relative Risk
plantains, underripe, raw	1.2	Lower
apples, gala	8.1	6.8x higher

Fructose raises uric acid independently of purines by accelerating purine degradation in the liver. The ACR 2020 guideline identifies high-fructose foods as independent gout risk factors. Choosing lower-fructose fruits helps manage uric acid without eliminating fruit from the diet.

How This Comparison Is Built

Every food in this comparison has been evaluated using a three-factor risk engine that independently assesses purine content, fructose level, and alcohol presence. Purine values come from two primary references — the USDA+ODS-NIH PURINE DATABASE Release 2 (March 2025) and Kaneko et al. (Biol Pharm Bull 37(5):709-721, 2014, PMID: 24553148). Fructose data is sourced from USDA SR28 Food Composition Tables. The verdict system follows ACR 2020 guideline thresholds: Safe (purine <50 mg, fructose <2g, no alcohol), Moderate (purine 50-150 mg or fructose 2-5g), Avoid (purine >150 mg, fructose >5g, or alcohol present). Data quality is labeled T1 (lab-measured), T2 (measured + consensus), or T3 (category estimate) on each food's detail page.

Frequently Asked Questions

Which has more fructose: plantains, underripe, raw or apples, gala?

apples, gala contains 8.1g fructose per 100g — 6.8x more than plantains, underripe, raw at 1.2g/100g. Fructose directly raises uric acid through hepatic ATP depletion, independent of purine content.

How does fruit fructose affect gout differently from purines?

Purines provide raw material for uric acid; fructose accelerates the body's own purine breakdown. A fruit can be low in purines but still raise gout risk through high fructose. The ACR 2020 guideline recognizes both as independent dietary triggers.
